APPARATUS FOR DRYING TEXT-HIE FABRICS.

. Application filed March 24,1926. Seria1 No. 96,96l 5.

This'invention relates to improvements in thetreatment of textilefabrics, and has particular reference to an apparatus for dryingfabrics. In my copending application, Serial N 0. 50,175, filed August14, 1925, allowed February 6,1926, there is described a machine whereinfabrics wound upon drums are passed through a plurality of baths toeffect the dyeing of the fabrics. After the dyeing process hasbeencompleted, it has been customary to convey the drums with thefabrics thereon to a drying room where the fabrics, while, on the drums,are subjected to the action of heated air. 7 This air penetrates thefabric fromboth the exterior of the roll and from the'inter'iorthereof,-

the drum being of an openwork construction. It has been found that theintermediate layers or convolutions of the roll of fabric do not becomethoroughly dried unless the fab ric is allowed to remain in the dryingroom for twelve hours or more.

An object of the present invention is to greatly facilitate the dryingof fabric on a drum by passing heated air from the interior of the drumoutwardly through the fab riethereon. V j 7 Another object is to closethe open ends of a drum by means of closure elements into which heatedair is injected under pressure, so that said air will pass through thedrum and the fabric thereon and thereby quickly and thoroughly dry saidfabric. The above and other objects will, appear more clearly from thefollowing detail description, when taken in connection with theaccompanying drawing, which illustrates preferred embodiments of theinventive idea.

In the drawing Figure 1 is an elevation, partly in section, of one formof apparatus for carrying out the invention;

Figure 2 is a section on the line 2-2 01 Figure 1; and

Figure 3 is a view similar to Figure 1 showing a slightly different formof apparatus.

Referring more particularly to Figures 1 and 2, the apparatus forcarrying out the invention is shown as consisting of a pair of standards4 each having a laterally extending support or bearing 5 at its upperend provided with a recess 6 in its extremity for receiving one of thetrunnions 7 of a drum 8 upon which the fabric 9 is wound. After the drumand fabric have been passed through the dyeing machine described in theabove mentioned application, said drum .is mounted between the'standards4 inthe manner above described preparatory to dryingthefabric. The drumsemployed with said dyeing machine are of openwork con struction andconsist of annular end memi bers 10 havingspacedradial braces 11 fromthe inner ends of which extend the trunnions 7. ,The end members areconnected by spaced strips 12 which combine to form the wall of the drumand about which the fabric 9 is wound. By thus providing an openworkconstruction of drum,'it will be apparent that heated air may pass intothe ends of the drum and from thence outwardly between the strips 12,"as indicated by the arrows in Figure 1.

Each of the bearingsli has secured thereto at 13 an endclosure 14 which,in the present embodiment, is made of a flexible material,

such as rubberized fabric or'the like,an'd

through whichthe heated .air cannot pass,

By making this end closure or hood of flexible material the same may beeasily fitted. over the adjacent end of the roll of fabric 9 mounted onsaid drum. A binding element 15, such as a cord, may then be tied aboutthe portion of the closure 14 which overlaps the end of the fabric rollso as to secure the closure in position and prevent the escape of heatedair between the same and the'outer surface of said roll. One of theclosures 14 is provided with an extension 16 forming an inlet to which ahose or other suitable connection 17 is attached for the purpose ofinjecting heated air into the compartment formed by the closure 14. Thehose 17 may be connected to any suitable source of heated air capable ofinjecting said air into the closure 14 under pressure. The air enteringthe closure 14 at the right of Figure 1 will pass through the adjacentend of the drum and some of said airwill enter and fill the loo driedthe binding elements 15 are removed to permit of the .detachmentof theend closures 14 from the fabric, after which the drum may be lifted fromits supports and the fabric 9 unwound therefrom.
